518525 - hang for 2-3s the first time a menubar is clicked Error: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIWebNavigation.sessionHistory]" nsresult: "0x80004005 (NS_ERROR_FAILURE)"

Status: RESOLVED DUPLICATE of bug 504670

(Firefox :: Menus, defect)

Description

[mmc]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3

I can reproduce this consistently (linux, FFx 3.5.3): after a startup, the first
time I click on the menubar Firefox freezes for about 2-3 seconds. The error
console shows the message:

Error: [Exception... "Component returned failure code: 0x80004005
(NS_ERROR_FAILURE) [nsIWebNavigation.sessionHistory]"  nsresult: "0x80004005
(NS_ERROR_FAILURE)"  location: "JS frame ::
chrome://global/content/bindings/browser.xml ::  :: line 641"  data: no]
Source File: chrome://global/content/bindings/browser.xml Line: 647

I have the ubiquity and firebug addons (not being used). I have also tried creating a new profile, but the problem remained.

Reproducible: Always

Steps to Reproduce:
1. Load up firefox
2. Click anywhere on the menubar (I usually click on bookmarks)
3. Firefox freezes for 2-3 seconds
Actual Results:  
If firefox is loading something, when the freeze happens everything stops, spinner included.


After the freeze, further clicks on the menubar do not cause it again, it all works as expected.
